Executive Summary

Indian Ocean

Maritime security in the Indian Ocean has further deteriorated, with attacks linked to the ongoing Hormuz crisis. Multiple vessels were targeted by projectiles and UAVs, including tankers and containerships, with several incidents resulting in onboard fires and structural damage.

Europe

European waters remain exposed to ongoing hybrid and kinetic threats linked to the Russia–Ukraine conflict. This week was marked by the seizure of a sanctioned shadow fleet tanker following an oil spill in the Baltic Sea, damage to a vessel during a large-scale Ukrainian drone and missile attack on Taganrog and sightings of unmanned surface vehicles approaching Crimea.

East Africa

The situation remains contained but sensitive, as the hijacked Iranian dhow continues to be used as a pirate mothership. Naval forces are actively tracking the vessel, and while no immediate threat to merchant shipping has been confirmed, the situation underscores the risk of piracy resurgence in the region.
